The Guyer, as it is generally referred to, is a bio-mechanical body armor of incredible strength, dexterity and firepower. From forearm blades to the all-powerful megasmasher, it is virtually invincible and self-regenerating (like Wolverine) unless its control metal is destroyed. But, the company that found it and two others, Chronos, wants it back and uses any means necessary to get it from the boy who found it. Either by kidnapping or using Zoanoids, genetically enhanced humans with massive strength.

Overall, it is an excellent series (12 episodes so far released) and he can be seen sort of as a perpetual tragic hero, as he is destroyed quite a few times. The battle scenes are very bloody and carnage filled (especially when the Guyver gets his brain smashed). There is some nudity, but is covered the waist down for males. There are a few quick shots of a females chest are seen but that is it. The plot and dialogue are better than average. The main characters all have distinct roles, and double-crossing and secret agent situations add surprise to the basic lineage of the story. The opening and ending sequences are very well made with the dialogue, and even though still in Japanese, they are addictive. Guyver is a must-see for superhero lovers.
